2 Claims.

mechanisms may be readily loaded for transport when not in use.

An additional object of the invention is the provision of such a device characterized by means whereby the truck may be readily adjusted from drag to transport position with a minimum of effort and dificulty.

A further object of the invention resides in the provision of means associated with such truck for readily and expeditiously securing drag sections thereto for use in harrowing a field.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings Figure l is a top plan view of the truck showing a plurality of towing means for drag harrows associated therewith in operative position.

Figure 2 is a sectional view taken substantially along the line 2-2 of Figure 1 as viewed in the direction indicated by the arrows.

Figure 3 is a fragmentary sectional view taken substantially along the line 3-3 of Figure l as viewed in the direction indicated by the. arrows.

Figure 4 is a fragmentary sectional view disclosing a constructional detail.

Figure 5 is a top plan view similar to Figure l, but showing the parts of the apparatus in transport position, the drag harrow sections being removed for the sake of clarity of illustration.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring now to the drawing, and more particularly to Figure 1, the device of the instant invention comprises a transport truck generally indicated at l0, and including a rectangular frame section comprised of front and rear transverse members II and I2, of angle iron or the like, connected at their extremities by end por tions l3, and provided with perpendicular wheel supporting and reinforcing members l4.

Angularly inclined towing members l5 are secured to the frame at the juncture of rear member l2 and intermediate members l4, and converge to an eye I 6, by means of which the device is adapted to be attached to a towing vehicle such as a tractor or the like.

A reinforcing member I! connects the members [5 at a point forwardly of the frame, while supplemental reinforcing and supporting members l8 extend from the juncture of members l5 and I! to the extremities of front members I I.

Angle iron member I? is provided on the rear of the frame, with a flange extending outwardly from the frame, and having a plurality of spaced apertures 20, adapted to be selectively engaged by hooks 2|, carried by chains 22, connected to single drag draw bars 23, provided with eyes 24, to which eyes are adapted to be secured drag harrows.

Extending members 21 are provided, also of angle iron construction, and are adapted to provide extensions for the width of the frame of the transport frame, permitting the association of additional drag harrows therewith.

Each member 21 is comprised of an elongated angle iron section, provided on its inner face with a plurality of apertures 28, in which may be selectively engaged a hook 29, secured to the end of a chain 30, which in turn is secured to a rod 3|, provided with a hook 32 adapted to engage in a suitable aperture adjacent the end 8f the vertical flange of strip iron front memer ll.

The inner end of each member 21 is provided with a hook 35 which may be engaged in a suitable aperture 36 in one of the members I5 adjacent its juncture with rear member l2, or which alternatively when the parts are in a different position of adjustment, may be engaged in an aperture 31 in an ear 38 secured to the inner or forward side of the vertical flange of rear member l2.

The vertical flange of member '27 is secured thereto adjacent the outer end thereof, and has facing rearwardly, a pair of apertured ears or lugs 39, Within the apertures of which may be secured the hooks 2| of a single draw bar 23, or alternatively hooks 40 secured to chains 4!, in turn secured to eyes 42, positioned at spaced intervals on a double draw bar 43, provided with eyes 44, to which may be secured drag harrow portions 45.

It will thus be seen that the arrangement of the device is sufiicient-ly flexible to permit the association of any desired number of drag harrows therewith from one to six as may be desired, the arrangement being indicated in Figure 1, wherein four of the six possible drag harrow attachments are provided.

The transport assembly is adapted to be carried on wheels 50, preferably rubber tired, to permit highway transport, which are mounted on stub axles 5|, comprising the right-angled eX- tremities of axle-supporting members 52, which terminate in oppositely disposed right-angled opposite extremities 53, secured in pivotal relation with the front frame member i i as'b a pinrality of curved bolts 54, secured in position as by nuts 55. I A triangular plate 55 is secured to each axle, and provided'with an aperture engaged by the extremity 51in pivotal relation, of a rod 58, the opposite end of which is provided with a rightangled portion +39 journalied for rotation in a suitable aperture inframe member i i.

A toothed quadrant ht is mounted on the stub axle 5!, the teeth of which are adapted to be engaged by a detenttl, carried b a rod 62, spring pressed inwardly into engagement with the teeth by means of a spring 83, and provided with a release handle 8 the rod and spring being secured insuitable brackets t5 carried by an operating handle member 56, provided with a right-angled'portion 6! adjacent theportion 5d, the arrangement being such that the compression of theportions 54 and '8'! releases the detents 5i from the teeth of the quadrant E9.

Obviouslyz'the arrangement is such that movementof the handle '65 and corresponding move ment'of triangular plate 55, will, through the pivotal connection of the members 52 and 58 vary the relative height of the entire frame assembly relative to the axles, and consequently, thedis'tance of the assembly above the ground.

7 The device-has hitherto been described in conjunction with Figure 1, that is, in operative position adapted for'the towing of drag harrows over the field or'the'like.

However, when it is desired to transport the harrowsfrom one locality to another, the frame ismaised in the manner previously described by means of thehandle 56, and the parts positioned in substantially the relation shown in Figure 5, theibars remaining secured to rear members i EIas-by their chains 22, and positioned in angular relation :across the members [15 and the ears 38. The-double draw bars 43,:and the extension members El are positioned in the manner as shown "forwardly-of the forward frame member i-rLandresting on-the angle ironsupports l5 and I8,

The drag -harrows may then be suitably positioned over the entire assembly, between the wheels 59, and the device is then ready to be towed to any desired locality.

Obviously, the parts may be permitted to merely rest on the frame on occasional short journeys, or may be suitably secured thereto as by wiring or roping if desired for longer journeys.

From the foregoing, it will now be seen that there is herein provided an improved transport for harrows which permits the ready packing and transporting of such harrows, without the necessity of utilizing a separate truck or other vehicle, and which accomplishes all the objects of this invention, and others, including many advantagesof great practical utilit in commercial importance.

As many embodiments may be made of this inventive concept, and as many-modifications may be made in the embodiment hereinbe'fore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.
